Chris Brown is at it again.

The hotheaded musician is under investigation for assault after brawling with R&B singer Frank Ocean outside of a Los Angeles recording studio Sunday night, officials said.

Witnesses told investigating deputies that the fight was over a parking space – and that Brown threw the first punch.

Those statements conflict with initial reports of the fight, with other witnesses telling TMZ that someone attacked Chris as he tried to shake Ocean’s hand.

Ocean, who cut his finger in the fight, took to Twitter following the melee: “got jumped by chris and a couple guys. lol. i only wish everest was there,” he wrote. Everest is the name of the singer’s Bernese mountain dog.

He also hinted that the injury could impact his performance at the Grammys.

The pair had previously battled online in 2011, back before Brown deactivated his Twitter account.

Last June, Brown and hip-hop star Drake were involved in a bottle-throwing melee at the Manhattan club W.i.P. Brown received a gash on his chin during that fight.

That club fight was reportedly over Rihanna, the longtime girlfriend Brown attacked in 2009.

In terms of this weekend’s fight, deputies are continuing to investigate, and they hope to talk to Brown. No charges have been filed at this time.
